How much energy is deposited in the body of a 78 kg adult exposed to a 2.9 Gy dose?
Please and thank you.
To calculate the amount of energy deposited in the body of an adult exposed to a certain dose of radiation, we need to use the concept of absorbed dose. Absorbed dose measures the amount of energy transferred to a mass of tissue per unit of mass, and it is typically measured in units of Gray (Gy).
The absorbed dose (D) can be calculated using the formula:
D = E / m
Where:
D is the absorbed dose in Gray (Gy)
E is the energy deposited in Joules (J)
m is the mass of the body in kilograms (kg)
In this case, we need to determine the energy deposited (E) when a 78 kg adult is exposed to a dose of 2.9 Gy.
Rearranging the formula, we have:
E = D * m
Plugging in the values:
E = 2.9 Gy * 78 kg
Calculating this multiplication:
E ≈ 226.2 Joules (J)
Therefore, the energy deposited in the body of a 78 kg adult exposed to a 2.9 Gy dose is approximately 226.2 Joules.
